Welcome to the AmpSeeker wiki!
- Create a new github repository using this workflow as a template.
- Clone the newly created repository to your local system, into the place where you want to perform the data analysis.
Configure the workflow according to your needs via editing the files in the config/
folder. Adjust config.yaml
to configure the workflow execution, and samples.tsv
to specify your sample setup.
Install Snakemake using conda:
conda create -c bioconda -c conda-forge -n snakemake snakemake
For installation details, see the instructions in the Snakemake documentation.
Activate the conda environment:
conda activate snakemake
Test your configuration by performing a dry-run via
snakemake --use-conda -n
Execute the workflow locally via
snakemake --use-conda --cores $N
using $N
cores or run it in a cluster environment via
snakemake --use-conda --cluster qsub --jobs 100
or
snakemake --use-conda --drmaa --jobs 100
If you not only want to fix the software stack but also the underlying OS, use
snakemake --use-conda --use-singularity
in combination with any of the modes above. See the Snakemake documentation for further details.
After successful execution, you can create a self-contained interactive HTML report with all results via:
snakemake --report report.html
This report can, e.g., be forwarded to your collaborators. An example (using some trivial test data) can be seen here.
Whenever you change something, don't forget to commit the changes back to your github copy of the repository:
git commit -a
git push
Whenever you want to synchronize your workflow copy with new developments from upstream, do the following.
- Once, register the upstream repository in your local copy:
git remote add -f upstream git@github.com:snakemake-workflows/AmpSeqVIGG.git
orgit remote add -f upstream https://github.com/snakemake-workflows/AmpSeqVIGG.git
if you do not have setup ssh keys. - Update the upstream version:
git fetch upstream
. - Create a diff with the current version:
git diff HEAD upstream/master workflow > upstream-changes.diff
. - Investigate the changes:
vim upstream-changes.diff
. - Apply the modified diff via:
git apply upstream-changes.diff
. - Carefully check whether you need to update the config files:
git diff HEAD upstream/master config
. If so, do it manually, and only where necessary, since you would otherwise likely overwrite your settings and samples.
In case you have also changed or added steps, please consider contributing them back to the original repository:
- Fork the original repo to a personal or lab account.
- Clone the fork to your local system, to a different place than where you ran your analysis.
- Copy the modified files from your analysis to the clone of your fork, e.g.,
cp -r workflow path/to/fork
. Make sure to not accidentally copy config file contents or sample sheets. Instead, manually update the example config files if necessary. - Commit and push your changes to your fork.
- Create a pull request against the original repository.
Test cases are in the subfolder .test
. They are automatically executed via continuous integration with Github Actions.
